摘　　要：针对航空发动机分布式控制系统的时延问题,应用Matlab的Truetime工具箱,设计了控制系统仿真分析平台,分析了时延对系统稳定性的影响。首先针对一类应用状态反馈的控制系统,分析了存在传感器到控制器单侧时延的情况下,系统保持稳定的充分条件。在此基础上,以某型航空发动机为例,基于Truetime工具箱设计了分布式控制仿真系统,分析了不同的时延条件对系统稳定性的影响。仿真结果与理论分析结果一致,证明了系统的有效性。With a focus on the problem of time delay of the aero-engine distributed system, a simulation platform is designed based on the Truetime tool box of Matlab,then the analysis of the effect of time delay on the performance of the system is carried out. Firstly, focusing on a kind of control system where state feedback is applied,the analysis is carried out on the sufficient conditions of the stability of the system where the time delay from sensor to controller exists. Secondly, an in-service aero-engine is used as an example to design the simulation system with the help of Truetime tool box. Finally, the analysis of the effect of time delay on the system performance is observed. The effectiveness of the simulation system got proved since the simulation results are consistent with the theoretical analysis.
